To all whom i' 15 may conce-rn Be it known that l, PHILIP J. hlnAHL, a citizen of the United States, and a resident of Bayonne, in the county of Hudson and State of Yew Jersey` have invented certain i .-w and useful Improvements in Perforated Music Roll Marking Machines, of which the following` is a. specification.

This invention relates to improvements in machines ior marking perforated music rolls such as are used on automatic or semiautomatic music playing devices.

it is customary to provide perforated music rolls, such as referred to above, with the dynamic and rhythmic signs or indications given by the composer on the staff notation so that as the perforated sheet when in use on a playingattachment passes the tracker these dynamic. or rhythmic. signs appeato view successively and give the performer or player the required information. Lines are also produ-ced on the sheets, extendingl lengthwise and laterally and by theiri'msitions on the tracker boardindirate louducss of playingcorresponding to the directions `given by the well known signs PP etc., to FF.

The object of mv invention is to provide a new and improved machine of simple construction, which rapit'lly, reliably and correctly prints such indications, and the line or either upon the perforated music roll.

in the accompanying drawings in which like letters ot reference indieee like parts in all the `figures: Figure 1 is a side, view of my improved machine for marking perforated music rolls, parts being broken away. Fig. 2 is a front elevation of the same. Fig. 3 is a detail view of part. of the pattern sheet.

'lhe endless pattern sheet 1 which consists of a sheet ot' paper or other suitable material, on which are produced in raised type the dynamic or rhythmic marks shown at and also in raised type an indicating li e i shown at 3, is passed over two drums -ra dv 5, the latter being mounted in standard) (3 and the former in a frame 7. The top part of the endless pattern sheet rests upon a suitable support or table 8 to prevent undue sagging. The drum or roller 4 is provided at its ends on its periphery with teeth 10` which can engage into openings 11 formed along the side edges of the pat-tern sheet in the nature of an endless rack so as to insure a uniform feed and movement.

The shaft- 12 of the drum et carries at one end a driving pulley 13 shown in dotted lines in Fig. but forthe purpose of clearness omitted from Fig. 1, and the opposite end of the shaft 12 carries a cog wheel 14 engaging a pinion 15 mounted on a shaft 16 in such a manner that it can vslide lengthwise en the shaft, but turns with the shaft. rlhis pinion is provided with a handle knobl 1T by means of which the pinion 16 can be temporarily withdrawn from engagement with the cog wheel 1l. suitable spring 1 8 serves to keep the pinion and cog wheel normally in engagement.

Gudgeons 9 of an impression roll 19 resting upon the top ofthe drinn l, that is, upon the pattern sheet at the top of the said drum are mounted in L-shaped arms 2O 'at the angles of said arms, which l.shapedV arms are each pivoted aty their upper end to the upper end of a curved standard or arm ou the top of the machine frame. On the shorter arm of each L-shaped arm 9-0, a cross head is formed, the ends of which at opposite sides of the machine are united by the bars Q3 forming a rectangular frame in which a. pressure `roller Q-l is mounted which pressed upon the periphery ofthe impression 'roll 19, by springs Q5 attached to the end pivots of the roller 2l and to the gudgeons 9. This pressure roller which is pressed upon the periphery of the 'impression roll 19 by springs 25 is so mounted in the :frame that its gudgeons or end pivots have a slight play in their openings, that is to say, the openings into which the said pins or gudgeons pass are so much larger than the pins that the pins can give slight-ly for a very minute distance and can be pressed by springs attached to the gudgeons of said roller 21 to exert the yielding pressure upon the paper 0n the impression roll 19 as stated above. The upper end of the cross heads are also connected by bars 26 with the L-shaped arms 20. Each curved standard or arm 21 is provided with horizontal brackets '27 in the upper edge of which an arc-notch 28 is formed and on the bottom of said notch the gudgeons 9 can rest. A set screw 29 extends into the bot.- tom of each notch and forms a' stop for the downward movement. of the gudgeons 9 and by means of these setscrews adjustment can be made so that the impression roll 19 will rest properly upon the paper on top'of the drum 4. The shaft 30 forming the pivots ou u'hieh the tfshupeil ziiius 2U swing iiioiuiied iii the upper ends of: the curved simular-ils 2l :uid carries the drum 3l pro vided with end-di 32 upon which the performed sheet to he ijirovided With ex pression lines und marks Woumh by rotsi;n me this drum hy means of :i heit passed over the pulley 533 ui' one end of the shaft 30 :is shown iu lfig. 2, which pulley, ifor clearhess, has also been omitted from Fig. l.
